I’m writing a horror novel, and I can’t think about what to call it! Here’s a general synopsis on it-

Ever since the accident, Erin Powell has been witnessing strange events of the paranormal type- and not just ghosts. With only her best friend, Will, on her side, can she figure out what is happening to her before things get dangerous?

Go back, after a week or two, and reread what you have written. There will be a word or phrase that strike you as a title. For example, while working on a story the sequence with a pathologist who is describing the condition of a faceless corpse uses the words “face value”. That then became the name for the story.
